A second man died Thursday after a shooting late last month during a dice game in the West Pullman neighborhood, authorities said.

An autopsy Sunday determined Kenneth Guise, 38, of the 1000 block of Sheridan Court in Kaukauna, Wis., died of complications of a gunshot wound to the head. He was shot Jan. 29 in the 11900 block of South Yale Avenue, according to the Cook County medical examiner's office.

Guise was pronounced dead at 6:22 p.m. Thursday at Advocate Christ Medical Center in Oak Lawn, according to the medical examiner's office, which ruled his death a homicide.

Mayron Collier, 24, also died during the attack and 27-year-old parolee Christopher Cage has been charged in that murder and is being held without bail at Cook County Jail since a Jan. 31 court hearing, records show.

Cage allegedly fatally shot Collier in the head "execution-style" after getting into an argument with him after a dice game during a party at a house on South Yale Avenue, according to Cook County Assistant State's Attorney Bob Groebner.

Collier lived in the 10000 block of South Pulaski Road, according to police and the Cook County medical examiner's office.

Cage then shot more than 10 rounds into a crowd at the house before shooting another man, Groebner said during the Jan. 31 court hearing. That man, who Groebner said at the time was 39 and on life support, was shot in the chest and taken to Advocate Christ hospital, police said.

Witnesses flagged a police car near the scene, and Cage was arrested. Witnesses identified Cage as the shooter, and Cage gave a video-recorded confession to the shootings, Groebner said.

Cage, of the 300 block of West 109th Place, was charged with first-degree murder and attempted murder, Chicago police said earlier.

As of Sunday night, there has not been an upgrade to Cage's charges.

In June, Cage was released from state prison on parole from a 2010 aggravated vehicular hijacking with a weapon conviction, according to records.
